Hello all, I am new to 3CX. Just installed last night, when I try to register an extension, I get an invalid password error in the phone settings. I have checked and re-rechecked the password on both, 3CX and phone, and still I keep getting the same error. By the way, this is an SNOM870 SIP phone. Here is the error that I get: 1003@99.XXX.223.XXX:5060: Invalid password provided Am I missing something simple here? Server Event log reports the following: SIP request (REGISTER) from 99.XXX.223.XXX was rejected. Reason: Block WAN requests is ON. 16:42:14.516 [CM102001]: Authentication failed for SipReq: REGISTER 99.XXX.223.XXX:5060 tid=-q5jbgv cseq=REGISTER firstname.lastname@example.org:2052 / 25265 from(wire); Reason: Credentials don't match, check that authorization-ID and password match the ones in extension settings Thank you.
